Organic-inorganic lead halide perovskite solar cells (PSCs) haveachieved impressive progress in both conversion efficiency and sta-bility. However, the leakage risk of toxic lead in the fabrication andservice of PSCs hinders their commercialization; hence, the manage-ment of lead is imperative. Here, we report a close-loop recyclingstrategy to collect the key materials involved in devices with butyl-amine (BA), even regenerating solar cells with recycled materialsincluding perovskite absorbers and NiOx-coated ITO glass sub-strates. The regenerated devices show performance equivalent tothat of fresh ones and nearly 18% PCE for the champions. The totalrecycling yield of lead is more than 98.9%. The recycling can beattributed to the unique interaction between lead halides and BA.Our strategy could move PSCs toward commercialization by effec-tive close-loop recycling and refabrication of whole PSC devices.
